The equivalent diameter is the diameter of a circular duct or pipe that gives the same pressure loss as an equivalent rectangular duct or pipe.. The table below can be used to compare equivalent diameters for rectangular and round circular ducts. The table is based on the ducts friction loss formula.. The rectangular dimensions and the air flow volume are adapted to the equal friction loss. Example of big metal round and rectangular ducts (3,000+ CFM airflow). To figure out exactly how big ducts you need for central air conditioning systems, we have prepared complete CFM duct charts for all different kinds of ducts:. Duct sizing chart for flex ducts (round ducts with 5-20 inch diameter).; Duct sizing chart for metal ducts (round ducts with 5-20 inch diameter) 4-5 inch (358) 5-Apr inch (43) Rectangular (947) Round (1563) Spiral (199) Product Type.

The velocity in a 12 inch duct with air flow 1000 cfm can be calculated as. Example - Air Flow Velocity in a Duct. The velocity in a rectangular 0.5 m x 0.5 m duct with air flow 1 m 3 /s can be calculated as. v m = (1 m 3 /s) / ((0.5 m) (0.5 m)) = 4 (m/s) Air Flow Velocity Calculator - SI Units Note that there is more than one possibility when switching from circular to rectangular ductwork.
